Answer:
[tex]5(56z - 5y - 6)[/tex]
Step-by-step explanation:
Forst step is finding a common factor, you can do this easily by looking at the ones digit. All 3 values end in 0 or 5, so a factor is definately 5.
We now divide all values by 5.
[tex]280z \div 5 = 56z \\ (- 25y) \div 5 = ( - 5y) \\ ( - 30) \div 5 = ( - 6)[/tex]
Once you get a prime number after factoring, that is the GCF, Greatest Common Factor. We can make an equation like what is below to show oir factored answer.
[tex]5(56z - 5y - 6)[/tex]
